7207L15JG

Overview

The Renesas Electronics Corporation 7207L15JG is a CMOS asynchronous FIFO memory device with a storage organization of 32K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The component utilizes a 32-pin PLCC surface-mount package and supports unidirectional data bus architecture. Designed for multiprocessing and rate buffering, it includes status flags such as Full and Empty to manage data flow.

Feature Summary

• Supports asynchronous and simultaneous read and write operations
• Includes retransmit capability for resetting the read pointer
• Utilizes Full and Empty status flags to prevent overflow and underflow

Applications

• Multiprocessing systems requiring high-speed data transfer
• Rate buffer applications between different clock domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply conditions. Confirm that the 32-PLCC package matches your PCB footprint requirements. Ensure compatibility with 5V logic levels and check for RoHS compliance documentation if required for specific regulatory standards before finalizing procurement decisions.

Selection Notes

Select this component when a 32K x 9 word depth is required for asynchronous buffering. The 15 ns access speed suits high-frequency data handling tasks. Consider the 32-PLCC package constraints for board layout. Verify that the unidirectional bus architecture aligns with system interface needs rather than bidirectional alternatives.

Part Context

This part belongs to the 7207L15 series of advanced CMOS FIFO memories manufactured by Renesas Electronics. It is functionally compatible with the broader 720X family, allowing for design flexibility across similar product lines. The device represents a specialized memory solution focused on efficient data management in complex electronic architectures.

Replacement Considerations

Check manufacturer documentation for officially recommended substitutes. Verify pinout and electrical parameter compatibility before integrating any alternative components into existing designs.
